The Fascial Distortion Model (FDM) is an anatomical perspective, originated by US physician Stephen Typaldos,
D.O., in which “the underlying etiology of virtually every musculoskeletal injury
(and many neurological and medical conditions) is considered to be comprised of one
or more of six specific pathological alterations of the body’s connective tissues
(fascial bands, ligaments, tendons, retinacula, etc.). As a model, the FDM is an
abbreviated interpretation of the pathology of fascial injuries and contemplates the
structural consequences of orthopedic, medical, surgical, and manipulative interventions.”
